     56=== LAMP CA ===
     57  * https://unis.incntre.iu.edu/protogeni/xmlrpc/lampca

    5659== 2.  Obtain slice of GENI resources, install and configure GEMINI I&M tools ==
     
    7881== 3.  Run and orchestrate GEMINI I&M tools and reference/actual experiment  ==
    7982
    80 === Verify passive measurements ===
    8183=== Configure active measurements ===
     84The tutorial directs me to configure one-way (OWAMP) and round-trip (Ping) latency regular tests according to the following diagram.
     85
     86  * Accessed psConfig UI
     87     Image
     88  * Enabled services on pca, pcb, and pcc and pushed configuration to UNIS
     89     Image
     90  * Configured regular active measurements according to diagram (above) and pushed configuration to UNIS
     91     Image
     92  * Applied configuration to the nodes
     93     Image
     94
     95=== Execute the reference experiment ===
     96   * Started the iperf server on PCC
     97{{{
     98[johren@PCC ~]$ iperf -s
     99------------------------------------------------------------
     100Server listening on TCP port 5001

     104   * Started the iperf client on PCA
     105{{{
     106[johren@PCA ~]$ iperf -c pcc -t 120 -i 12
     107}}}
     108   * Started the Phoebus gateway on PCB
     109{{{
     110[johren@PCB ~]$ sudo /etc/init.d/phoebus start
     111[johren@PCB ~]$ tail -f /var/log/phoebus.log
     112}}}
     113   * Introduced network impairments
     114      * For this step I had to create an SSH key pair for user johren and install them in ~/.ssh/authorized_keys on PCA and PCB
     115      * I also had to set the SSH config in ~/.ssh/config to use the new private key when contacting these hosts:
     116{{{
     117Host PCA
     118   IdentityFile ~/.ssh/phoebus
     119Host PCB
     120   IdentityFile ~/.ssh/phoebus
     121}}}
     122      * I then ran the "user" version of the setup_netem script
     123{{{
     124[johren@PCA ~]$ sh /tmp/setup_netem_user.sh
     125Setting PCA->PCB link to 5ms latency and .01% loss
     126Setting PCB->PCC link to 50ms latency and no loss
     127done
     128}}}
     129   * Again, ran the iperf client on PCA
     130   * Enabled phoebus gateway on PCB
     131{{{
     132[johren@PCA ~]$ setenv LD_PRELOAD /usr/lib64/libxsp_phoebuswrapper.so
     133[johren@PCA ~]$ setenv XSP_PATH pcb/5006
     134}}}
     135
     136   Insert picture of log here
     137
     138   * Again, ran the iperf client on PCA
     139   * Stopped phoebus service on PCB and iperf server on PCC
     140{{{
     141[johren@PCB ~]$ sudo /etc/init.d/phoebus stop
     142}}}

    83144== 4.  Observe I&M measurement results on GEMINI presentation service  ==
    84145
    85 Right now, the presentation service is the web server on the UW.  I observed the results by
    86 pointing the browser at http://localhost/oml.html
     146=== Observe passive measurements ===
     147==== Observe sidebar graphs for each node ====
     148  * For each node (PCA, PCB, PCC)...
     149    * click on node in Map view
     150 Insert image here
     151    * select graphs individually and make graphs show up on the left
     152Insert image here
     153    * select All Graphs and make sure all graphs show up in separate tab
     154Insert image here
     155    * Select VNC and make sure I can log in to the node
     156Insert image here
     157
     158  * Access the Passive UI on MC node
     159  * For each node (PCA, PCB, PCC)...
     160    * View all graphs
     161    * View all tables (compare to command line results; ifconfig, arp, lsmod, etc.)
     162       Insert image here
     163    * Connect VNC
     164       * VNC connection does not appear
     165       Insert image here

     182    * Graphs and tables viewable in the GEMINI portal
    93183
    94184== 5.  Push I&M measurement and analysis results to iRODS archive service  ==
    95185
    96 Used the i-command iput to push the analysis image to iRODS.
